Abstract:

A sprayable emulsion is provided. The emulsion can be used in the treatment of various skin conditions. The emulsion includes a hydrofluoro-based propellant, an emulsification system, an oil phase, a water phase, and active agent particles. Further, the emulsification system includes at least one nonionic emulsifier. The emulsion has a viscosity ranging from about 500 centipoise to about 10,000 centipoise and a hydrophilic to lipophilic balance (HLB) value of from about 2 to about 12. The present inventors have found that by selectively controlling the nature of the emulsification system and the viscosity of the emulsion, the active agent particles resist settling such that a substantially homogeneous distribution of the active agent particles is maintained and can be evenly sprayed onto a surface without running once applied.

Abstract:

A sprayable zinc oxide composition is provided. The sprayable zinc oxide composition can be used in the treatment of various skin conditions. The sprayable zinc oxide composition includes zinc oxide particles and a fluoro-olefin propellant. The present inventors have found that by selecting a propellant having a certain specific gravity, vapor pressure, and molecular weight, and by controlling the viscosity of the various components of the composition, the resulting zinc oxide composition resists settling such that a substantially homogeneous distribution of zinc oxide particles is maintained and can be evenly sprayed onto a surface without running once applied.

Abstract:

A spray delivery system including a sprayable active agent composition housed within a container is provided that can be used in the treatment of various skin conditions. The composition includes a hydrofluoro-based propellant, a carrier fluid, and active agent particles, and has a viscosity ranging from about 500 centipoise to about 10,000 centipoise. The container includes a dip tube; a valve assembly that includes a valve body, a stem comprising a stem orifice, and a vapor tap; and an actuator. The dip tube is coupled to the actuator by the valve assembly, and the actuator is depressed to dispense the emulsion. By selectively controlling the components and viscosity of the composition and the dimensions of the container components, the active agent particles resist settling so a substantially homogeneous distribution of the particles is maintained. Thus, the composition can be evenly dispensed from the container as a fine mist without clogging.
